As far as i understand the activation group fires only one rules for a given group. But does it run once for each fact inserted or only just once. for example i have activation group act1 with 3 rules: rule1,rule2,rule3 and inserted 4 facts . But the rule1 runs only once , i wanted rule1 to run for each of the 4 facts inserted. -- View this message in context: http://drools.46999.n3.nabble.com/Activation-group-doubt-tp4030388.html Sent from the Drools: User forum mailing list archive at Nabble.com.
